[0004] When the mechanical lock or the electronic lock is damaged due to external force, the non-working personnel can directly open the box door to tamper with the wiring in the meter box, thereby causing the electricity theft behavior. SUMMARY

[0085] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0086] Referring to Figure 1 A method for preventing electricity larceny of a meter box, comprising:

[0087] Step 100: Collecting the lock state of the door of the meter box.

[0088] The door lock state refers to the opening and closing state information of the locking structure on the metering box for locking the box door. When the locking structure is started, it means that the box door is locked, and it is difficult to open the box door at this time. When the locking structure is closed, it means that the box door is not locked, that is, the staff opens the metering box door. The collection method of the door lock state is selected by the staff according to the actual situation, which is not described here.

[0089] Step 101: When the door lock state is consistent with the preset locking state, the vibration amplitude of the metering box is collected.

[0090] The locking state refers to the door lock state when the locking structure is started. The locking state is selected by the staff according to the actual situation, which is not described here. The door lock state is consistent with the locking state, which means that the metering box door is closed at this time, and it is necessary to detect whether there is a situation of forcibly opening the box door by non-staff. The vibration amplitude refers to the vibration amplitude value of the metering box door, which can be detected by the vibration sensor uniformly arranged on the box door. The vibration sensor is at least three, and the collection method of the vibration amplitude is selected by the staff according to the actual situation, which is not described here.

[0091] Step 102: If the vibration amplitude is greater than the preset vibration threshold, the vibration duration is determined based on the vibration amplitude.

[0092] The vibration threshold refers to the minimum vibration amplitude that can damage the locking structure. The vibration threshold is selected by the staff according to the actual situation, which is not described here. The vibration amplitude greater than the vibration threshold represents that the vibration is relatively violent at this time, which can easily lead to the damage of the locking structure. The vibration duration is the duration when the vibration amplitude is greater than the vibration threshold. The determination method of the vibration duration is known to those skilled in the art, which is not described here.

[0093] Step 103: The interference coefficient is determined in combination with the vibration amplitude and the vibration duration.

[0094] The interference coefficient refers to a value for showing the total damage of the vibration to the locking structure. The sum of the vibration amplitude within the vibration duration can be calculated as the interference coefficient. The calculation method of the interference coefficient is known to those skilled in the art, which is not described here.

[0095] Step 104: In response to the interference coefficient, generate and display the electricity stealing prompt information.

[0096] The electricity stealing prompt information refers to information for showing the damage of the vibration to the locking structure to the staff. The generation method of the electricity stealing prompt information is known to those skilled in the art, which is not described here.

[0097] The vibration of the metering box is monitored in real time, so as to determine the damage of the vibration to the door of the metering box, and then timely inform the staff when the damage of the vibration to the metering box is too high to cause the failure of the protection measures of the metering box, so as to reduce the occurrence of electricity stealing behavior and improve the safety of the metering box.

[0098] The electricity stealing prevention method of the metering box further comprises:

[0099] Step 105: selecting a checking frequency based on the interference coefficient.

[0100] The checking frequency refers to the frequency of checking the protection effect of the door of the metering box. The greater the interference coefficient, the greater the influence of the vibration on the locking structure, and the greater the checking frequency required to prevent damage to the locking structure. The checking frequency corresponding to the interference coefficient can be queried from a frequency correspondence table, which is a data table recording different interference coefficients and their corresponding checking frequencies.

[0101] Step 106: collecting the door image of the metering box according to the checking frequency.

[0102] The door image refers to the picture of the door of the metering box, which can be collected by a camera fixed in the metering box. The collection method of the door image is selected by the staff according to the actual situation, and will not be described here.

[0103] Step 107: identifying the deformation coefficient of the metering box door from the door image.

[0104] The deformation coefficient refers to a numerical value for showing the deformation degree of the door. The greater the deformation degree, the greater the deformation coefficient. The deformation coefficient can be determined by image recognition technology. The determination method of the deformation coefficient is known to those skilled in the art, and will not be described here.

[0105] Step 108: determining the deformation difference value based on the deformation coefficient.

[0106] The deformation difference value refers to the change amount of the deformation coefficient, i.e. the difference between the deformation coefficient after the vibration and the deformation coefficient before the vibration. The calculation method of the deformation difference value is selected by the staff according to the actual situation, and will not be described here.

[0107] Step 109: determining the deformation matching degree in response to the deformation difference value and the interference coefficient.

[0108] The deformation matching degree refers to a numerical value for showing the influence of the vibration on the deformation of the box. The greater the deformation difference value and the smaller the interference coefficient, the greater the deformation matching degree. The deformation matching degree corresponding to the deformation difference value and the interference coefficient can be queried from a matching correspondence table, which is a data table recording different deformation difference values and interference coefficients and their corresponding deformation matching degrees.

[0109] Step 110: When the deformation matching degree is greater than the preset interference threshold, generating and displaying electricity stealing alarm information based on the deformation matching degree.

[0110] The interference threshold refers to the deformation matching degree used to determine whether the vibration is used to damage the box door. The interference threshold is selected by the staff according to the actual situation, which is not described here. The deformation matching degree greater than the interference threshold represents that the vibration is used to damage the box door, that is, the risk of intentionally damaging the box door by non-staff is greater.

[0111] The electricity stealing alarm information refers to the information used to show the damage of the metering box by non-staff to the staff. The generation method of the electricity stealing alarm information is known to those skilled in the art, which is not described here.

[0112] When the vibration of the metering box is more serious, the deformation of the metering box door is recognized through image recognition, so as to determine the damage degree of the vibration to the box door, and then when the damage degree of the box door is high, it is determined that someone intentionally causes vibration to damage the metering box, and the staff is notified in time, thereby improving the safety of the metering box.

[0113] A method for preventing electricity stealing of a metering box, further comprising:

[0114] Step 111: When the door lock state is consistent with the preset locking state, determining the vibration center according to the vibration amplitude.

[0115] The vibration center refers to the position of the vibration source, that is, the vibration center can be determined by the difference in vibration amplitude detected by sensors at different positions. The determination method of the vibration center is known to those skilled in the art, which is not described here.

[0116] Step 112: Determine the vibration distance based on the vibration center and the vibration amplitude.

[0117] The vibration distance refers to the distance between the sensor detecting the vibration amplitude and the vibration center. The determination method of the vibration distance is known to those skilled in the art, which is not described here.

[0118] Step 113: Determine the attenuation coefficient in response to the vibration distance.

[0119] The attenuation coefficient refers to a value that shows the attenuation of the vibration from the rotation center to the position where the sensor is located. The attenuation coefficient corresponding to the vibration distance can be queried from the attenuation corresponding table. The attenuation corresponding table refers to a data table recording different vibration distances and their corresponding attenuation coefficients.

[0120] Step 114: Determine the corrected amplitude by combining the attenuation coefficient and the vibration amplitude.

[0121] The correction amplitude is the amplitude of the vibration center predicted according to the attenuation of the vibration, and the quotient of the vibration amplitude and the attenuation coefficient can be calculated as the correction amplitude.

[0122] Step 115: updating the vibration duration according to the correction amplitude.

[0123] The vibration is prone to attenuation when it is transmitted to the sensor. The vibration situation collected by the sensors arranged at multiple points is used to determine the center of the vibration, so as to calculate the vibration situation of the center of the vibration, thereby improving the accuracy of identifying the electricity stealing behavior.

[0124] Referring to Figure 2 , the vibration influence correction method comprises:

[0125] Step 200: determining the locking component based on the vibration center when the door lock state is consistent with the preset locking state.

[0126] The locking component refers to the locking structure component in which the vibration center is located, such as a lock cylinder and a lock tongue. The locking component corresponding to the component range in which the vibration center falls can be queried from the component record table. The component record table refers to a data table recording different locking components and their corresponding component ranges.

[0127] Step 201: determining the influence coefficient based on the locking component.

[0128] The influence coefficient refers to a numerical value used to show the protection of the locking component against vibration. The greater the damage of the vibration to the locking component, the greater the influence coefficient. The influence coefficient corresponding to the locking component can be queried from the influence correspondence table. The influence correspondence table refers to a data table recording different locking components and their corresponding influence coefficients.

[0129] Step 202: calculating the product of the interference coefficient and the influence coefficient, defining it as the damage coefficient, and determining the damage threshold based on the locking component.

[0130] The damage coefficient refers to a numerical value used to show the damage of the vibration to the locking component. The calculation method of the damage coefficient is selected by the staff according to the actual situation, which is not described here.

[0131] The damage threshold refers to the minimum damage coefficient at which the locking component is difficult to realize its function, i.e., the damage coefficient of the damaged locking component. The damage threshold corresponding to the locking component can be queried from the damage correspondence table. The damage correspondence table refers to a data table recording different locking components and their corresponding damage thresholds.

[0132] Step 203: if the damage coefficient is greater than the damage threshold, determining the damage degree in combination with the damage coefficient and the damage threshold.

[0133] The damage coefficient greater than the damage threshold represents that the locking component is damaged due to the vibration at this time, that is, the locking structure has failed, and the damage degree refers to a value for showing the degree of damage of the locking structure, and the difference between the damage coefficient and the damage threshold can be calculated as the damage degree, and the greater the damage degree represents the more complete the damage of the locking component, and then the more difficult the locking component is repaired.

[0134] Step 204: generating and displaying a door lock damage prompt in response to the damage degree.

[0135] The door lock damage prompt refers to information for showing the damage of the locking structure to the staff, and the generation method of the door lock damage prompt is common knowledge of those skilled in the art, which is not described here.

[0136] The meter box is generally locked by multiple mechanical structures, each mechanical structure is affected by vibration to different degrees, the center of the vibration is compared with the positions of the mechanical structures to evaluate the damage of the vibration to each mechanical structure, so as to inform the staff when the structure is completely damaged, and improve the safety of the meter box.

[0137] The vibration influence correction method further comprises:

[0138] Step 205: If the damage coefficient is greater than the damage threshold, determine the conduction route in combination with the vibration center and the preset terminal position.

[0139] The terminal position refers to the position of the line terminal in the meter box, and the terminal position is selected by the staff according to the actual situation, which is not described here. The conduction route refers to the shortest route of the vibration from the vibration center to the terminal position, that is, the route of the vibration on the box body, and the determination method of the conduction route is common knowledge of those skilled in the art, which is not described here.

[0140] Step 206: determining the conduction coefficient based on the conduction route.

[0141] The conduction coefficient refers to a value for showing the attenuation of the vibration on the conduction route, and the longer the conduction route and the closer to the ground, the more difficult the vibration is to propagate, and then the smaller the conduction coefficient is. The total length of the route and the passing position of the route can be counted from the conduction route, and then the sum of the distances of each position from the ground is calculated as the ground distance from the passing position, and finally the conduction coefficient corresponding to the total length and the ground distance is queried from the conduction correspondence table, and the conduction correspondence table refers to a data table recording different total lengths, ground distances and corresponding conduction coefficients.

[0142] Step 207: calculating the product of the interference coefficient and the conduction coefficient, and defining as the conduction vibration.

[0143] The conduction vibration is a value showing the influence degree of the vibration conduction to the terminal after the vibration conduction to the terminal, and the calculation method of the conduction vibration is well known to those skilled in the art, which is not described herein.

[0144] Step 208: determining the loosening degree according to the conduction vibration and a preset loosening threshold.

[0145] The loosening threshold refers to the minimum conduction vibration required for the terminal to be completely loosened, and the loosening threshold is selected by the staff according to the actual situation, which is not described herein. The loosening degree refers to a value showing the loosening situation of the terminal, and the quotient of the conduction vibration and the loosening threshold can be calculated as the loosening degree. If the loosening degree is 1, it means that the terminal is completely loosened. The calculation method of the loosening degree is selected by the staff according to the actual situation, which is not described herein.

[0146] Step 209: generating and displaying a terminal loosening prompt in response to the loosening degree.

[0147] The terminal loosening prompt refers to information for showing the loosening situation of the terminal to the staff, and the generation method of the terminal loosening prompt is well known to those skilled in the art, which is not described herein.

[0148] The vibration on the metering box body is easy to be conducted to the circuit inside the metering box. According to the center where the vibration is generated, the route of the vibration conduction to the circuit inside the metering box is planned, so as to calculate the vibration conduction to the circuit, and then timely inform the staff when the vibration causes the circuit to be loosened, thereby improving the safety of the metering box.

[0149] Reference Figure 3 The metering box protection method comprises:

[0150] Step 300: collecting the metering temperature if the damage coefficient is greater than the damage threshold.

[0151] The metering temperature refers to the temperature value inside the metering box, which can be detected by the temperature sensor uniformly arranged in the metering box. The collection method of the metering temperature is selected by the staff according to the actual situation, which is not described herein.

[0152] Step 301: determining the in-box temperature distribution of the metering box based on the metering temperature.

[0153] The in-box temperature distribution refers to the distribution of the temperature in space, which can be analyzed by the difference of the metering temperature detected by the temperature sensors at different positions. The determination method of the in-box temperature distribution is well known to those skilled in the art, which is not described herein.

[0154] Step 302: determining the temperature concentration point according to the in-box temperature distribution.

[0155] The temperature concentration point refers to a position in the metering box where heat is emitted, i.e., a peak point in the temperature distribution in the box. The determination method of the temperature concentration point is well known to those skilled in the art, and will not be described here.

[0156] Step 303: determining the heat-emitting component and the component temperature based on the temperature concentration point.

[0157] The heat-emitting component refers to a component in the metering box where the temperature concentration point is located, such as a terminal, a circuit breaker, an electric energy meter, etc. The heat-emitting component corresponding to the heat-emitting area where the temperature concentration point is located can be queried from a heat-emitting record table. The heat-emitting record table refers to a data table recording different heat-emitting components and heat-emitting areas corresponding thereto. The component temperature refers to the temperature value at the temperature concentration point, which can be read from the temperature distribution in the box. The determination method of the component temperature is well known to those skilled in the art, and will not be described here.

[0158] Step 304: determining the temperature interval according to the heat-emitting component.

[0159] The temperature interval refers to the temperature variation range of the heat-emitting component. The historical temperature of the heat-emitting component can be retrieved, and the highest temperature and the lowest temperature in the historical temperature are selected as the upper limit and the lower limit of the temperature interval. The determination method of the temperature interval is selected by the staff according to the actual situation, and will not be described here.

[0160] Step 305: determining the heat-emitting difference value in combination with the temperature interval and the component temperature.

[0161] The heat-emitting difference value refers to a numerical value showing the degree of temperature abnormality of the component, i.e., the difference between the component temperature and the temperature interval. The calculation method of the heat-emitting difference value is well known to those skilled in the art, and will not be described here.

[0162] Step 306: determining the electricity stealing situation in response to the heat-emitting component and the heat-emitting difference value when the heat-emitting difference value does not fall within a preset fluctuation interval.

[0163] The fluctuation interval refers to a temperature range in which the heat-emitting component is prone to fluctuation with external conditions. The fluctuation interval is selected by the staff according to the actual situation, and will not be described here. The heat-emitting difference value not falling within the fluctuation interval represents that the temperature fluctuation of the heat-emitting component is relatively severe, i.e., the heat-emitting component is abnormal. The electricity stealing situation refers to the behavior of stealing electricity. For example, when the terminal temperature of the power input end of the metering box is too low, it may be that the user has drawn electricity from the power input end, resulting in a decrease in the current at the terminal of the power input end. The electricity stealing situation corresponding to the heat-emitting component and the heat-emitting difference value can be queried from an electricity stealing corresponding table. The electricity stealing corresponding table refers to a data table recording different heat-emitting components and heat-emitting difference values and electricity stealing situations corresponding thereto.

[0164] Step 307: updating the electricity stealing alarm information according to the electricity stealing situation.

[0165] When the locking structure of the meter box is damaged, the meter box is at high risk of electricity theft, at this time, the temperature distribution in the meter box is detected through the sensor, so that when the line of the meter box is abnormally heated, it is judged that there is electricity stealing behavior, and then the staff is notified in time, and the safety of the use of the meter box is improved.

[0166] The meter box protection method further comprises:

[0167] Step 308: When the heating difference does not fall into the preset fluctuation interval, the meter box number is called.

[0168] The meter box number refers to the number used to distinguish the meter box, and each meter box number corresponds to a meter box. The calling method of the meter box number is selected by the staff according to the actual situation, which is not described here.

[0169] Step 309: Based on the meter box number, the area reading and the meter reading are called.

[0170] The area reading refers to the electric energy reading of the meter box corresponding to the meter box number read from the area total meter. The meter reading refers to the electric energy reading of the meter box corresponding to the meter box number. The calling method of the area reading and the meter reading is selected by the staff according to the actual situation, which is not described here.

[0171] Step 310: Calculate the difference between the area reading and the meter reading, and define it as the reading error.

[0172] The reading error refers to a value used to show the difference between the readings of the area total meter and the meter box. The calculation method of the reading error is well known in the art, which is not described here.

[0173] Step 311: If the reading error is greater than the preset electricity stealing threshold, determine the error duration based on the reading error.

[0174] The electricity stealing threshold refers to the minimum change value of the meter reading when the meter box is stolen from the power input end. The electricity stealing threshold is selected by the staff according to the actual situation, which is not described here. The reading error greater than the electricity stealing threshold represents that the meter reading difference is too large, that is, there may be electricity stealing behavior. The error duration refers to the duration when the reading error is greater than the electricity stealing threshold. The determination method of the error duration is well known in the art, which is not described here.

[0175] Step 312: When the error duration is greater than the preset response threshold, update the electricity stealing alarm information in response to the reading error.

[0176] The response threshold refers to the minimum time length required for the meter reading to change accordingly when the electric energy change of the transformer area is transmitted to the meter box. The size of the response threshold is related to the distance between the meter box and the transformer area. The response threshold is selected by the staff according to the actual situation, and will not be described here. The error time length greater than the response threshold represents that the meter reading continues to have errors after excluding the influence of electric energy transmission, that is, there is electricity stealing behavior from the incoming end of the meter box.

[0177] When the components in the meter box abnormally heat, the electric energy readings of the transformer area and the meter box are compared, so that when the reading gap is too large, it is judged that there is electricity stealing behavior, and the electricity stealing situation is estimated according to the reading gap to timely inform the staff, thereby improving the safety of the meter box.

[0178] The meter box protection method further comprises:

[0179] Step 313: When the error time length is greater than the preset response threshold, the electricity stealing component is determined according to the electricity stealing situation.

[0180] The electricity stealing component refers to the meter box component that has electricity stealing behavior. For example, when the electricity stealing behavior is bypassing from the outgoing end of the meter box, the electricity stealing component is the outgoing end terminal of the meter box. The determination method of the electricity stealing component is known to those skilled in the art, and will not be described here.

[0181] Step 314: If the electricity stealing component is consistent with the preset outgoing component, the power-off interval is determined in response to the heating difference value.

[0182] The outgoing component refers to the output component of the meter box to the outside world, that is, it includes the outgoing end terminal, the outgoing end interface and other components. The outgoing component is selected by the staff according to the actual situation, and will not be described here. The consistency of the electricity stealing component and the outgoing component represents that the electricity stealing personnel steals electricity from the outgoing end of the meter box. The power-off interval refers to the time interval of periodic power-off to force the electricity stealing personnel to stop stealing electricity. The greater the heating difference value, the more serious the electricity stealing situation, and the greater the power-off interval needs to be. The power-off interval corresponding to the heating difference value can be queried from the power-off corresponding table. The power-off corresponding table refers to a data table recording different heating difference values and their corresponding power-off intervals.

[0183] Step 315: Determine the power transmission process based on the power-off interval.

[0184] The power transmission process is the power transmission process of the meter box periodically powered off according to the power-off interval. The determination method of the power transmission process is known to those skilled in the art, and will not be described here.

[0185] Step 316: Control the meter box to transmit power according to the power transmission process.

[0186] When the user steals electricity from the power outlet of the meter box, the appropriate power-off interval is selected according to the electricity stealing situation, so as to control the meter box to periodically power off, thereby forcing the user to stop stealing electricity and improving the safety of the meter box.

[0187] The meter box protection method further comprises:

[0188] Step 317: If the damage coefficient is greater than the damage threshold, identify the opening and closing parameters of the box door from the box door image.

[0189] The opening and closing parameters refer to the opening and closing of the box door, which can be determined by image recognition technology. The determination method of the opening and closing parameters is well known to those skilled in the art and will not be described here.

[0190] Step 318: When the opening and closing parameters are consistent with the preset door opening parameters, update the box door image.

[0191] The door opening parameters refer to the opening and closing parameters when the box door is opened. The door opening parameters are selected by the staff according to the actual situation and will not be described here. The consistency of the opening and closing parameters and the door opening parameters represents that the box door is opened, and at this time the locking structure is not opened, which represents that the box door is forcibly opened by non-staff at this time.

[0192] Step 319: Identify the electricity stealing behavior from the box door image, and determine whether the preset face feature exists in the box door image.

[0193] The electricity stealing behavior refers to the tampering behavior of non-staff to the meter box. The components tampered by non-staff to the meter box can be identified as electricity stealing behavior by image recognition technology. The determination method of the electricity stealing behavior is well known to those skilled in the art and will not be described here.

[0194] Step 320: If the preset face feature exists in the box door image, control the preset light device to start, and identify the electricity stealing personnel from the box door image.

[0195] The face feature refers to the feature parameter of the clear face identified by image recognition technology. The light device refers to the equipment fixed in the meter box for illuminating the outside. The face feature and the light device are selected by the staff according to the actual situation and will not be described here. The existence of the face feature in the box door image represents that the clear face can be identified from the box door image. At this time, the light device is started to improve the clarity of the face in the box door image. The electricity stealing personnel is the face image of non-staff extracted from the box door image by image recognition technology. The determination method of the electricity stealing personnel is well known to those skilled in the art and will not be described here.

[0196] Step 321: Update the electricity stealing alarm information in combination with the electricity stealing behavior and the electricity stealing personnel.

[0197] When electricity theft is detected, the system identifies and records the damage to the metering box by the electricity thief from the image. It also identifies the face of the electricity thief in the image and controls the lights to be activated when a clear face appears in the image to capture a clear image of the electricity thief's face, which facilitates subsequent processing of the electricity theft.
